2. Description of the Related Art
The distributed FA information management system in the manufacturing industry is a system based on a client-server model, and needs to access a server (storage device) in order to access information possessed by the system.

The information content in the server is subjected to predetermined information processing such as statistics such as production results and operation results that can be predicted in advance, comparisons, evaluations, and the like, and an operator can extract necessary data from the information. .

In such an FA information management system,
Suitable for routine information processing (permanent routine information such as direct report, daily report, monthly report) and data processing with high frequency of reuse, but recognizes the current situation required for improvements and improvements frequently made in the manufacturing industry. Collection of operation information and quality / QA information for
Or, it is not suitable for handling irregular and unpredictable data processing, such as improvement of manufacturing methods and equipment, and collection of evaluation data after improvement.

In addition, it is difficult to implement a function from the viewpoint of cost reduction for data processing that is used only for a short period of time and is infrequently used, for example, it is necessary to know only during a trial operation or to check only immediately after a change in a manufacturing process. Often.

That is, the data necessary for improving the production control varies depending on the processes to be improved and improved, and data at the end that does not remain as data in the server (for example, dimensions and the like measured at the time of transporting the raw material). ) Is required, a specific worker must be placed in a predetermined process to obtain the data. Further, when and where a trouble occurs cannot be predicted, and it is almost impossible to store this in the server in advance as raw information.

As described above, due to the variety of data requirements, the difficulty of prediction, the complexity of the database and the file structure, and the opacity of the processing history, it is impossible to manage data with a low reuse frequency by the server.

The present invention has been made in consideration of the above facts, has solved the drawbacks of the conventional client-server model, and has been able to easily input information according to a request to an operator in a plurality of steps of manufacturing a product, thereby improving and improving the present invention. It is an object of the present invention to provide an FA information management method capable of quickly performing predetermined information processing such as statistics, comparison, evaluation, and the like necessary for production management such as.

[0009]

According to a first aspect of the present invention, raw information in a plurality of steps of manufacturing a product or a message group in which raw information is appropriately classified is transmitted to a data transmission network of a network, and the raw information or Specifying and capturing a message group, executing new information processing that cannot be predicted in advance based on the captured raw information or message group,
It is characterized by:

According to the first aspect, the raw data or raw information of the manufacturing process, which has not been processed (information obtained as a result of data processing), is appropriately classified in the data transmission network of the network. Messages are flowing
By specifying and capturing this raw information or message group, new information processing that cannot be predicted in advance can be executed.

Here, as a well-known technique, if processed information (message group) is flowing through a data transmission network and necessary information is randomly taken from this message group, any processing is performed. It is also an easy technique to freely extract unprocessed raw information or messages.

In the first invention , new information processing that cannot be predicted in advance is executed based on the extracted raw information or message group. In other words, the fetching of raw information or messages to obtain statistics, comparisons, evaluations, etc., required at this time, and the execution of processing based on this raw information, etc., have no effect on other devices connected to the network. Can be performed without giving

As described above, it has been extremely difficult to quickly and easily deal with various demands in the future in a system based on the conventional client-server model, whereas in the present application, the immunity of living organisms is described in the present application. As with models, for various foreign antigens, instead of genetically preparing antibody production information based on past experience in advance, genetic recombination is performed at the time of antibody cell proliferation, and various foreign antigens are prepared. It is in accordance with the mechanism of dealing with.

That is, in order to be able to respond to various data processing demands expected in the future, instead of preparing prepared data in advance, a broadcast type (or address server) directly flowing on a network is used. Attention is paid to the message group and the raw information contained in the message group, and when it is necessary to process the raw information contained in the message group, a storage device and a storage method suitable for the data amount and processing are prepared. Independent of the existing storage device, it directly accesses raw information or messages on the network to collect and process data. By having such a mechanism, knowledge of the structure of files and databases of existing storage devices, access methods, processing histories, etc. becomes unnecessary. It can respond flexibly and quickly.

According to a second aspect of the present invention, a plurality of processes for manufacturing a product are summarized, raw information in each process is collected, and predetermined information processing such as statistics, comparisons, and evaluations that can be predicted in advance is performed.
A FA information management method for managing each process based on the information processing, wherein the raw information transmitted to a data transmission network of a network is captured by designating a collection timing and a period as necessary. New information processing different from the information processing that cannot be predicted in advance based on the obtained raw information is executed independently.

According to the second invention, the technique of the first invention is directly applied to a system based on the conventional client-server model, and the data transmission network on the network of this system can be freely accessed. It becomes possible. Further, there is no adverse effect on the conventional system.

The raw information can be classified into a plurality of predictable message groups including process / control information, quality, QA information, operation information, and trouble information.

[0018] Raw information is processed / processed information, quality, Q
A information, that operation information, previously classified into a plurality of group of messages that can be predicted in advance including trouble information, which is advantageous during the search and the like.

According to a third aspect of the present invention , a plurality of processes for manufacturing a product are summarized, raw information in each process is collected, and predetermined information processing such as statistics, comparisons, and evaluations that can be predicted in advance is performed.
An FA information management method for managing each process based on the information processing, wherein the raw information is classified into a plurality of message groups by a combination which can be predicted in advance, and the classified message groups are transmitted to a data transmission network of a network. The message is included in the message group or the message group by designating at least the message group transmitted to the network data transmission network or the combination of each raw information included in the message group and, if necessary, the collection timing and period. New information that cannot be predicted in advance is independently generated based on raw information to be generated.

According to the third aspect , the conventional client-server model performs predetermined information processing such as statistics, comparisons, and evaluations that can be predicted in advance, and manages each process based on the information processing. It is possible with a system based on. Here, the system can be further provided with direct access to raw information or messages to the network / data transmission network without affecting the system. Therefore, a combination can be specified for each message group or each piece of raw information included in the message group. Note that the collection timing and period can be specified as needed.

Next, predetermined processing is performed on the basis of the specified and imported raw information (or message group) to obtain new information. In this case, the data collection period (short period, middle period, long period) can be freely selected, and data can be obtained for quick improvement and improvement of the manufacturing process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an F according to an embodiment of the present invention.
A block diagram of a flow-oriented system 10 for implementing an A information management system is shown.

In this embodiment, a bus-type network will be described. However, the form of the network is not limited to the bus-type network, but may be a loop-type, star-type, mesh-type, or root-type. 1 surrounded by a dotted line in FIG.
0 is an existing client server model system.

As shown in FIG. 1, a sequencer 14 is connected to the bus 12, and the sequencer 14 controls the exchange of signals between the line 16 in the manufacturing process and the bus 12. The sequencer 14 stores a sequence program for each manufacturing process (or for each subdivided process classified in the same manufacturing process), and each process is controlled by the sequence program.

In each process, PI / O18, SERVO20, SENS
OR 22 is connected to line 16 and sequencer 14
Each device operates in response to an instruction from.

Between the bus 12 and the line 16 of the manufacturing process, there is provided a router 24 as a relay device for facilitating the transmission of information. Etc. are transmitted to the bus 12.

A plurality of terminals (DTE) 2 are connected to the bus 12.
6, 28 and 30 are connected, and their roles are
The monitoring of each process (production, operation information, quality, QA information, process / control information, trouble information) is mainly performed by accessing the server computer 32 described later.
It is performed by management of predetermined quality data.

The following are representative examples of the predetermined quality data. (1) Aggregate and compare specific sizes. (2) Aggregate and compare by product group. (3) Aggregate and compare by unit. (4) Aggregate and compare for each shift. (5) Aggregate and compare specific sizes for each worker.

The items (1) to (5) are production and operation results, and data is periodically collected, stored for a long period of time, and stored in a database (or server).

The printer 34 connected to the terminal 30 outputs (prints) a trend graph, a bar chart, a pie chart, a comparison table, a raw information list, and the like based on the quality data as described above.

In order to arrange the quality data, information is taken in, processed and stored by the server computer 3.
2 and each processing information is stored in the server 36.
And are stored collectively. The server computer 32 is connected to each terminal 26 connected to the bus 12,
28 and 30 are accessible.

This is a system based on the existing client-server model, and as described above, the predetermined quality data (processed data) is stored as shared data.

[0033] Contrary to the advantage that such shared data is suitable as long-term storage data, since it is already processed data, there is a disadvantage that raw information necessary for improvement and improvement cannot be extracted. is there.

Therefore, in the present embodiment, a dynamic information space formed by a group of messages flowing through a network / data transmission network is defined as a primary shared information space, and a static information space stored in a storage device group is defined. The information space is defined as a secondary information space. The secondary information storage space newly includes a storage device group called a stock that permits duplicate storage, and also includes an existing storage device.

That is, based on a so-called two-layer information space design method (flow-oriented system) in which a primary shared information space shared by the entire system is designed first, and then a stock is designed as necessary. We are building a system.

In order to realize this system, the bus 1
2, it is necessary to flow raw information from each manufacturing process.
The group of messages flowing through the bus 12 is defined as a primary shared information space.

As shown in FIG. 1, three terminals 40, 42 and 44 are newly installed as a part of the secondary information storage space. The terminals 40, 42, and 44 are classified into stock 1, stock 2, and stock 3, respectively. The terminal 40 of stock 1 is suitable for short-term (instantaneous) storage.

The stock 42 terminal 42 is suitable for medium-term storage. The following data is suitable for short-term / medium-term memory. (6) Compare data before and after process improvement. (7) Evaluate the data before and after the machine improvement. (8) When changing the work method, compare the data before and after the change. (9) Ascertain the quality outlier ratio for a certain period in terms of% or number. (10) When starting up machinery, grasp the quality status. (11) Compare differences between lots. (12) Ascertain time-series changes in lots.

(6) to (12) are data at the time of improvement, improvement, change, and start-up. Data is collected irregularly, stored in the short term and the medium term, and stored in the stocks 1 and 2. It should be noted that the short term and the medium term are not strictly distinguished from each other, but are selected as required for production quality control.

The terminal 44 of the stock 3 is suitable for long-term storage, and includes the above-described quality data (1) to (5).

In addition to the above, short-term memory mainly includes cases where an early discovery of the cause of a trouble is required and urgent improvement or improvement is necessary, and medium-term memory such as temporary troubleshooting Unstable period from to permanent troubleshooting, ie
At times when it is not possible to predict in advance, there are cases where limited data due to trouble is required, and as a long-term memory, to meet the ever-changing needs of the manufacturing industry, processing that could not be predicted at first Data may be added as and when it becomes necessary, independent of and without any effect on the programming of the server computer 32.

The operation of the present embodiment will be described below. If a trouble occurs during operation, naturally, a production manager or the like rushes to the site to investigate the cause of the trouble. Conventionally, in order to investigate the cause, data is collected from the server 36 of the server computer 32, and it is determined from what point in time what kind of change has been observed in which step. If it can be determined from the data from the server 36, there is no particular problem.
You will be collecting data. For example, when the width dimension of a product is required, conventionally, the server computer 32 requires a great deal of man-hours to create or modify the software in order to access it, despite the numerical values being input. Instead of designing software, a new sensor has to be installed, or the sensor has to be branched off from the signal line of the existing sensor, and measurement has to be performed directly at the site.

However, in the present embodiment, all the raw information is sent to the bus 12, and it is possible to directly access the bus 12 and take in the necessary raw information. In addition, necessary information can be obtained even if the user is away from the site.

For such urgent data management,
The terminal 40 of the stock 1 is applied. In other words, the amount of data is not so much required, and a generally available data management software program is applied, and new processing information (in the above case, the meandering degree of the transport system is determined from the width dimension data) based on the raw information. Change rate). This allows
For example, measures such as provision of a guide plate temporarily to reduce the meandering degree can be obtained quickly.

The raw information is classified into message groups through the message group classification means, and the message groups are sent to the bus 12. The terminal 40 has a message search function and a message binding function.

As shown in FIG. 2, it is composed of a list of raw information (definition information) classified for each message group. Therefore, even if the user does not need to remember the file name or the like attached to each piece of raw information, the user can easily search for the necessary raw information / message group from the list and specify it with the pointer,
You can make a specification. Raw information / message groups that are not in the list can be added later.

The message binding function has the following (1)
Processing is performed by designating from (4) definition information (My Agent) (primary processing). (1) Designation of desired message group (2) Designation of message acquisition start / end conditions (time, specific message, etc.) (3) Combination for combining a plurality of acquired message groups to perform primary processing as a new message Specifying the method. (4) Designation of primary processing method-Message storage medium, database / EXCEL format file, DOS file, etc.-Data editing method at the time of storing a message: When data in message is stored after processing by four arithmetic operations, etc. Primary processed information In the terminal 40, various editing processes (secondary processing) are performed by general-purpose package software.
The link of the general-purpose package of the primary processed information can also be performed by the definition information.

Next, what is needed is data during an unstable period from temporary troubleshooting to permanent troubleshooting. In this case, a medium-term memory is required, and the terminal 42 of the stock 2 is applied.

The terminal 42 of the stock 2 naturally needs a larger type and amount of raw information than the terminal 40 of the stock 1. That is, even if the direct cause is meandering, it is necessary to pursue an indirect cause such that the cause of the meandering is the temperature control in the previous process.

For this reason, the current process and the previous process are linked, and limited elements (raw information) are required. Such necessity of information cannot be predicted at the beginning of the programming of the server computer 32. It is. Therefore, the data stored in the server 36 cannot be processed.

In the terminal 42 of the stock 2, by incorporating a program for information processing suitable for each manufacturing process, a relatively large amount of data is prepared, and new processing information is linked to a plurality of processes. Can be generated.

Thus, for example, taking the above meandering measures as an example, by lowering the temperature control threshold value in the previous step by X%, deformation due to uneven temperature can be eliminated, and meandering can be eliminated. Measures can be determined quickly and accurately.

After the permanent countermeasure, the terminal 44 of the stock 3 is used for long-term management in order to determine whether or not each process operates smoothly. After such countermeasures are of course unpredictable at the beginning of operation, incorporating them into the program of the server computer 32 requires an enormous amount of time and effort, and is far from quick response.

On the other hand, in the terminal 36 of the stock 3,
It is completely irrelevant to the server computer 32, and a program for generating new processing information based on raw information necessary for the current permanent countermeasures may be set up, and a quick response can be taken.

Further, in the current manufacturing industry, many kinds of small quantities are commonplace, and the products themselves change steadily, so that the work process is improved and the cycle of improvement is accelerated. A change in the programming of the server computer 32 to cope with this cannot be followed, which is a serious problem in production management. However, the flow-oriented system 10 according to the present embodiment can sufficiently follow such an early changing cycle. Further, since each piece of processing information remains in an independent form, unnecessary processing information may be deleted.

As described above, the flow-oriented system 10 according to the present embodiment can quickly and accurately obtain request data that changes every moment. Even in an emergency, for example, the improvement and improvement can be performed without delay, and the product yield can be improved.

Also, since it is possible to obtain necessary raw information by accessing the bus 12 remotely even if not at the site, it is necessary to separately obtain necessary data in each field such as design, production management, and manufacturing technology. Can be obtained, and it is no longer necessary to rely on a small number of system engineers managing the server computer 32.

Also, as shown in FIG.
By connecting to a telephone line via a CE (data line terminating device) 50, it is also possible to centrally manage the management of factories nationwide and worldwide.

In this embodiment, the stock 1
The terminal 40, the terminal 42 of the stock 2, and the terminal 44 of the stock 3 are described as being juxtaposed in the drawing, but this is for convenience, and any terminal may be connected as long as it is connected to the bus 12. . Further, the functions of the terminals 40, 42, and 44 can be integrated into one or several terminals, and may be detachable. Further, conventional terminals 26, 28, 30 may be applied.

There is an excellent effect that predetermined information processing such as statistics, comparisons and evaluations can be performed quickly.

In addition to the above effects, in the second aspect, the present invention can coexist with a system based on the conventional client-server model, and can freely access a data transmission network on a network without adversely affecting the conventional system. be able to.
